Schedule October 3-5

This minicourse is for those who are just starting out with COMSOL Multiphysics® or want a refresher on the graphical user interface (GUI) and modeling workflow. During this session, the fundamentals of using the COMSOL® software will be demonstrated.

In this minicourse, you will learn about modeling conductive and convective heat transfer with COMSOL Multiphysics®, the Heat Transfer Module, the CFD Module, and the Subsurface Flow Module. Conductive heat transfer modeling addresses heat transfer through solids and can include heat transfer in thin layers, contact thermal resistance, and phase change. Convective heat transfer addresses heat transfer in solids and fluids. We will also address natural convection induced by buoyancy forces.

Whether you choose to construct a geometry in the COMSOL Desktop® or import it from a CAD file, this minicourse will demonstrate some useful tools. Did you know that COMSOL Multiphysics® can automatically generate the cross section of a solid object and you can use it for a 2D simulation? Or that you can directly import topographic data to create 3D objects? Generating a geometry is also about preparing selections for physics settings. By using the right selection tools, you can easily automate the modeling workflow, even when this involves simulations on widely different versions of a geometry. Attend this minicourse to see a demonstration of these techniques and more.

In this minicourse, we will cover the Microfluidics Module, which features custom interfaces for the simulation of microfluidic devices and rarefied gas flows. Single-phase flow capabilities include both Newtonian and non-Newtonian flow. Beyond its single-phase flow capabilities, this module also allows for two-phase flow simulations to capture surface tension forces, capillary forces, and Marangoni effects. Typical applications include lab-on-a-chip (LOC) devices, digital microfluidics, electrokinetic and magnetokinetic devices, inkjets, and vacuum systems.

In this minicourse, we will address the modeling of resistive and capacitive devices with the AC/DC Module. We will also cover the calculation of electric fields under steady-state, transient, and frequency-domain conditions, as well as the extraction of lumped parameters such as capacitance matrices. Applications include the modeling of resistive heating and sensor design.

The nonlinear strain-rate- and temperature-dependent response of polymers can be accurately captured using the COMSOL Multiphysics® software, either through the built-in material models or the PolyUMod library (linked to the COMSOL Multiphysics® software via the External Material Model interface). In this workshop, we will demonstrate how to accurately predict the thermomechanical response of different polymeric materials, including cases where we recommend material models from the PolyUMod library. The examples will include all steps, from experimental testing and material model selection and calibration to COMSOL Multiphysics® software simulations.

Magnetic fields arise due to magnets and the flow of current. In this minicourse, you will learn about using the AC/DC Module to model static, transient, and frequency-domain magnetic fields that arise around magnets and coils. We will introduce various ways of modeling magnetically permeable materials, motors, and generators.

In this minicourse, we will walk you through the meshing techniques that are available to you in the COMSOL Multiphysics® software. We will introduce you to basic meshing concepts, such as how to tweak the meshing parameters for unstructured meshes. More advanced topics include working with swept meshes and creating mesh plots. You will also learn a useful technique for meshing imported CAD designs: How to hide small geometry features from the mesher.

Radiative heat transfer is one of the three types of heat transfer and plays a major role in many applications. During this session, we will focus on the features for modeling surface-to-surface radiation for gray surfaces or multiple spectral bands, such as solar and infrared radiation. We will discuss different examples in order to help identify cases where thermal radiation has to be accounted for.

Defining ambient conditions is a key point in the model definition, especially when solar radiation is accounted for, but there are also other cases. We will review the different means to define the ambient condition and how use them for conduction, convection, and radiation in heat transfer models.

Learn how to efficiently simulate incompressible and compressible turbulent flows in this CFD minicourse. The CFD Module allows for accurate multiphysics flow simulations, such as conjugate heat transfer with nonisothermal flow and fluid-structure interactions. We will also discuss physics interfaces for simulating flow in porous media, discrete and homogeneous two-phase flow, and flow in stirred vessels with rotating parts.

COMSOL Multiphysics® gives you precise control over the way in which your multiphysics models are solved. In this minicourse, we will cover the fundamental numerical techniques and underlying algorithms used for steady-state models and explain the reasons behind the default solver settings. Building upon this knowledge, you will learn various techniques for achieving or accelerating convergence of nonlinear multiphysics models.

Additive manufacturing (AM) offers an almost unparalleled opportunity to produce complex three-dimensional objects with minimal waste and without significantly increasing production costs. AM technology has matured from its origins in manufacturing prototypes to the successful production of customized, commercial-scale products. During this time, it has demonstrated the potential to transform the rules of component design and manufacture by reducing or eliminating the constraints of traditional molds, presses, and dies. In this discussion, we will examine the current trends in AM and the role of virtual prototyping in extending the impact of this transformative technology.

The Application Builder, included in the COMSOL Multiphysics® software, allows you to wrap your COMSOL Multiphysics® models in user-friendly interfaces. This minicourse will cover the two main components of the Application Builder: the Form Editor and the Method Editor.

We will discuss applications in resonant cavity analysis, antenna modeling, transmission lines and waveguides, and scattering. Then, we will address the coupling of electromagnetic wave simulations to heat transfer, such as in RF heating.

Many different physical phenomena are coupled to the deformation of solids. In this minicourse, you will get an overview of how to model fluid-structure interaction, thermal stresses and thermoelastic damping, electromechanical forces, magnetostriction, piezoelectricity, poroelasticity, and acoustic-structure interaction. The built-in multiphysics couplings are highlighted, together with examples of how to create your own couplings.

Legislation for air pollution and carbon dioxide emission targets have accelerated the development of hybrid and electric cars. This development has also put focus on battery and fuel cell research and development, where modeling and simulation are proven methods for obtaining fast results. In this session, we will discuss the latest requirements and the trends regarding the processes — for example, thermal management, performance degradation, short circuiting, and fast recharge — which are important to study through modeling and simulations.

Changes in the temperature of a material can lead to a change in material phase, from solid to liquid to gas. The evaporation and condensation of water are very common cases of phase change. This minicourse will introduce you to moisture transport and the various types of phase change modeling that can be done with COMSOL Multiphysics® and the Heat Transfer Module. We will address the relative merits and tradeoffs between these techniques.

Join this update training minicourse to learn about major upgrades to the electromagnetics simulation tools. Both low- and high-frequency modeling capabilities will be covered. Products featured include the AC/DC Module, RF Module, Wave Optics Module, and Ray Optics Module.

Virtual prototypes and digital twins play a major role in the development process across industries. This is also true when dealing with acoustics, from designing audio systems in cars and optimizing miniature transducer performance in mobile devices to designing muffler systems. Common to these applications is the need to use different modeling strategies depending on the frequency range, model size, and details included in the physics used. The integration of simulations and testing is also important.

Abbott’s Mechanical Circulatory Support group build implants that help people suffering from heart failure, a deadly and increasingly common disease. We combine computational fluid dynamics and particle tracing simulations to optimize the designs of implantable blood pumps that replace the left heart function. In an example, we will showcase HeartMate 3™, a blood pump with a magnetically levitated rotor and arguably the most complex machine ever implanted into a human being.

In the aerospace and wind turbine fields, implementing a suitable lightning protection design is paramount. Lightning, and other electromagnetic effects (precipitation static, radiated fields, etc.), can seriously degrade performance, damage, or even destroy objects without an acceptable protection design. In the past, to determine the threat that lightning poses, several iterations of engineering testing were required to obtain data, which drives the protection features an object must have to survive. This is a high-risk path and can result in tremendous program costs and setbacks. Multiphysics modeling allows for the effects of lightning to be understood without having to perform dozens of test iterations and frequently results in large time and cost savings for programs that use it. In this talk, the role of multiphysics in the development of lightning protection designs and the certification of these designs is discussed as well as the benefits of this approach.

A new pedagogical approach to STEM challenges is currently implemented in the mechanical engineering program at the University of Hartford. This approach combines problem- and inquiry-based learning, simulations and apps with the COMSOL Multiphysics® software, and emphasizes the importance of outside-of-class learning supported by effective reference materials and faculty mentoring.

A two-course sequence was modified to contain scaffolded and contextualized simulations with application building that develop technical competency in modeling, a deeper understanding of thermofluids concepts by solving realistic technological problems, and writing skills by generating technical reports for each simulation. Apps involve creating a simplified interface that contains the full efficacy of the underlying model but not exposing the end user to its complexity.

Abstract: No matter how well COMSOL developers build COMSOL Multiphysics®, there are times when the software does not respond the way the user desires. Often, these unexpected responses are driven by user input. This class addresses methods to identify user mistakes during model development based on feedback provided by the software. The course material will provide valuable insights into interpreting errors, warnings, and other feedback from COMSOL Multiphysics®. Utilizing our experience and extensive use of the software as a COMSOL Certified Consultant, this course will examine common error messages and provide solutions to understanding and addressing these issues.

In this minicourse, you will learn how to define and solve problems in electrodeposition, corrosion protection, and corrosion studies. These systems all involve mass and charge transfer coupled to electrochemical reactions at deforming metal surfaces. We will look at two different approaches: one that treats the surface deformation as a variable and a second approach that treats the surface deformation with moving mesh. The most common type of study for these systems is the time-dependent study, but we will also briefly look at electrochemical impedance spectroscopy (EIS) studies.

In this minicourse, we will study different classes of problems involving acoustic propagation in fluids. This ranges from propagation in large domains, such as rooms or the ocean, to transmission through small perforations where thermal and viscous losses are important. Detailed modeling of the propagation in moving fluids is also discussed. This is, for example, the case in a muffler with a nonisothermal background flow. You will also learn about recent news and additions to the COMSOL Multiphysics® software relevant to the topic. Application areas include, but are not limited to, muffler design, sound insulation materials, room and car acoustics, and flow meters.

Solving large and complex finite element models can take significant time and computational resources. In this minicourse, we will address the modeling techniques that you should be aware of and then go into the choice of solvers for large models. We will cover the differences between the various solvers in the COMSOL Multiphysics® software in terms of their time and memory usage. Additonally, solver performance is inextricably linked to computer architecture. This course will cover how factors such as memory bandwidth, processor speed, and architecture address solution times.

Lagrangian particle tracking is often used as a complement to Eulerian methods that solve for fluid flow fields. In this course, we will explain how to use the Particle Tracing Module to predict the motion of solid particles, droplets, and bubbles in a surrounding fluid. We will outline some of the myriad built-in forces included in the Particle Tracing for Fluid Flow interface, including lift, drag, electromagnetic, thermophoretic, and acoustophoretic forces.

Signal Microwave designs and builds coaxial connectors for microwave and high-speed digital applications. This includes wireless systems, radar, 5G, optical systems, test equipment, back planes, etc. The COMSOL® software is one of our core technologies and is used to design virtually every product we make. This presentation will show how COMSOL Multiphysics® is integrated into our design process and allows us to develop excellent products with a faster design cycle time. A pair of examples will be given, showing how COMSOL Multiphysics® allowed us to minimize the development time, troubleshoot machined material, and meet our customers’ requirements.

Next-generation synchrotron light sources are creating orders-of-magnitude brighter X-rays by reducing horizontal emittance. This requires the bending magnet pole tips to be closer to the electron beam axis, which in turn requires smaller vacuum chambers. The resultant design challenges are dictated by complex and coupled physical phenomena, including high thermal stresses, photon-stimulated desorption, and electromagnetic wakefields. The Application Builder in the COMSOL Multiphysics® software enables the creation of browser-based graphical user interfaces (GUIs), which enable scientists and engineers to study this complicated problem domain without becoming an expert user of the COMSOL® software. With a relatively inexpensive COMSOL Server™ product license, these GUIs can be run on a cloud-based server, with many processors and all of the required RAM for complex simulations. This approach extends the power of COMSOL Multiphysics® to collaborators, customers, students, etc. We present two such GUIs: 1) the emission of synchrotron radiation and resultant thermal stress on vacuum chamber walls that are downstream of dipole bending sections, and 2) accurate thermal analysis and optimized mechanical bending correction for high-heat-load beamline mirrors. The various challenges of creating the underlying FEA models and the methods used to overcome them will be discussed. Both examples are relevant to the Advanced Photon Source upgrade (APS-U) under construction at Argonne National Laboratory.

We will discuss application areas including cameras, telescopes, laser focusing systems, spectrometers, and concentrated solar power systems. You will also learn how to apply the Ray Optics Module in a multiphysics context by considering structural and thermal effects.

This course builds upon the Solving Larger Models minicourse and addresses how to select hardware for computationally challenging multiphysics models. Solver performance is inextricably linked to computer architecture and this course will cover how factors such as memory bandwidth, processor speed, and architecture address solution times.
